Does anyone know of a bent with pedals that just push in and out, back and forth, not round and round? I am looking for a Taiwanese one I heard about but have been unable to find. I am a partially disabled vet and cannot do the rotating pedal thing. www.bettermotiongroup.com, out of Canada, has one they call "Hiker". I can't afford the $1800 they want. Their website has some cool videos though so you can see what kind of pedals I am talking about. Any info would be vastly appreciated. Thanks in advance.
